Elcometer 3025 Scratch Tester

Product Description

The Elcometer 3025 Scratch Tester is a motorised device to test the resistance of many materials to scratching, shearing, gouging, marring, scraping and engraving. This portable instrument tests materials up to 12.7mm thick by 101mm square or round. The height of the scale beam is adjusted by the user to match the thickness of the sample. The tool, a conical diamond tip, is then placed on the sample and the instrument is activated by the user with the On/Off switch.
The tip leaves a trace mark and the extent of this, in relation to the load used, indicates the degree of hardness. The turntable rotates at a constant 5rpm to ensure repeatability and reproducibility of tests. By changing the load on the tool, from 0-1000g, the sample’s resistance to deformation can be evaluated.

The Elcometer 3025 Scratch Tester can be used in accordance with:
